SEWAGE-DISTRIBUTER.

Specification of Letters Patent.

Patented Aug. 4, 19114.

Application filed October 10, 1913. Serial No. 794,473.

To all whom it may concern:

lie it known that we, JonN \VILLIAM Ilanrnny and CYRIL J OI-IN Hiurrnny,subjects of the King; of Great Britain, both residing at Stone,Staffordshire, England, have invented certain new and usefulImprovements in Sewage- Distributors, of which the following is aspecification.

This invention relates to sewage and like liquid distributors in whichthe liquid is intermittently fed under a falling head, for instance froma dosing chamber, to a number of nozzles fitted with deflectors or dashplates in order to disperse the liquid in the form of dome shaped jets,which due to the falling head gradually decrease in diameter.

The objects of the present invention are to produce dome shaped jets inthe form of sheets or films without the formation of fine spray, inorder to avoid aerial nuisance, to insure that the jets will maintain asubstantially unbroken form during practically the whole feeding: periodand during; which they are contracting, and to insure practicallyuniform distribution around each nozzle particularly as regards the areanearer the nozzle, which area in known distributers is usuallyovcrdosed, or as in the case of siphon distributors is sometimesinsufficiently dosed.

Figure 1 is a sectional elevation of the lower part of a dosing chamber,and Fig. 2 a. sectional view of the nozzle and pivotal support for thespreader plate.

In carrying the invention into effect according to the form shown, thedosing chamber a, which is a vertical chamber adapted to receive adefinite quantity of sewage, is provided at its base with a contractedportion 30. The sewage is supplied through a supply pipe 0 controlled bya tubular valve y. From the contracted base of the dosing chamber a, apipe (Z also leads to the nozzle 1 shown in Fig. 2. The valve y isbalanced and of tubular form and guided in guides 9 which are supportedon the inset piece 29 in the dosing chamber which effects thecontract-ion of the dosing chamber on its base. The valve y is adaptedto seat on a valve seat 4. A similar construction is provided forcontrolling the outlet of the sewage from the dosing chamber 66 throughthe outlet pipe (Z. The definite quantity of sewage under the fallinghead has to be evenly distributed in small quantities over a definitearea.

It is sought by means of the present invention to distribute the sewagein a dome shaped fihn and not in the form of a spray, so as to avoidaerial nuisance and smell. For this purpose the upwardly turned nozzle fwhich of considerable cross-section has a spreader plate n of convexform supported in spaced relation directly opposite the nozzle and at apoint where the stream has not started to break up, that is to say at apoint where the stream under the action of the head has still an upwardmovement in rope form. The dash plate a is provided with sharp knifeedges at its periphery as indicated at 11. so that the short inclinedfaces a slope away from the film of liquid, leaving the spreader platea. In this way all capillary action is avoided at this point and thefilm leaves the spreader plate in an unbroken form and passes as a domeor ulnbrella shaped stream on to the distributing bed.

The plate a is supported from an arm 0' extending from the under convexsurface and. pivoted. about the pivot t which is mounted on a log a onthe side of the nozzle 7'. The arm 0 is provided with a stop '12 adaptedto strike. against the wall w of the nozzle f. This stop locates theproper position of the spreader plate over the nozzle. By using a knifeedged arm 0 which cuts the stream or sheet of liquid, while it is stillin. contact with the spreader plate a and is therefore of considerablethickness, all liability to break the stream is avoided and this,together with the uniform distribution, is the main object of thepresent invention.

It is to he noted that in order to produce the desired effect ofspreading the water in a domeshaped sheet without fine spray on itsupper surface, in the most elficient manner, experiment has shown thatthe periphery of the spreader plate should have an acute knife edge suchas forms part of the present invention. The pivotal arrangement of thespreader plate enables the same to be removed readily to one side toclean out the nozzles f,

1. In a sewage disposal apparatus, means for uniformly distributingsewage over a defipite area including an upwardly turned nozzle to whichthe liquid passes under pressure, a substantially convex spreader platefacing the opening of said nozzle and in spaced relation thereto, saidspreader plate arm extending radially of the lower convex side of saidspreader plate to intersect the 15 stream of liquid before it leaves theconvex surface.

In testimony whereof We have signed our names to this specification inthe presence of two subscribing witnesses.
